CORD HOLDER FOR S ELF -BHNDERS.

SPECIFICATION forming part of Letters Patent No. 328,918, dated October 27,1885.

Application filed July 2, 1883.

To all whom it may concern:

Be it known that I, WILLIAM BUTTERFIELD, of Auburn, of New York, have invented certain Improvements in Cord-Holders for Self-Binding Harvesters, of which the following is a specification.

My invention has reference to that class of machines wherein a rotary tying-bill is employed in combination with a rotary notched disk which clamps and holds the cord or other binding material.

The aim of the invention is to provide a simple and positively-acting means for imparting the required intermitting rotation to said devices.

To this end the invention consists, substantially,in the combination,with the cord-clamp ing disk and the rotary tying-bill, of a wheel provided with suitable teeth and delay-surfaces to actuate the tyer, and also with a spiral thread adapted to impart an intermittent r0- tation to the disk, and in minor details,which will be hereinafter pointed out.

Referring to the accompanying drawings, I have represented my improvements constructed with special reference to their application in a binder of the well-known Appleby type, such as represented in its leading features in Patent No. 212,420; butthe details may be modified to adapt the devices for application to other binders without changing the mode of action or departing from the limits of the invention.

Figure 1 represents a top plan view of the tyer, clamping-wheel, and attendant parts of the machine, the threaded wheel being arranged to act directly upon the clampingdisk. Fig. 2 represents a similar view with the threaded Wheel arranged to operate the clamping-disk through an intermediate pinion. Fig. 3 is a face view of the actuatingwheel in its preferred form, differing slightly from those represented in the preceding figures. Fig. 4 is a diagram illustrating the action of the wheel represented in Fig. 3 upon the notched or toothed clampingdisk.

Referring to Fig. 1, A represents a rigid bracket forming part of the frame adapted to encircle the main shaft B, and to sustain the in the county of Cayuga and State Serial No. 99,812. (No model.)

rotary tying-bill O and notched cord-clamping disk D. The tyer, of ordinary form, is provided with the usual driving-pinion and delay-surface, and is driven intermittinglyby teeth and delaysurfaces formed, as usual, upon the wheel E, secured on the main shaft. The clampingdisk, pivoted centrally to the axis. on the frame, is provided with peripheral eord-receiving notches c, and arranged to revolve at one edge in a grooved jawin substantially the ordinary manner. In addition to the usual notches, c, it is provided with intermediate notches, d, to receive the operating thread or lip, the peripheral portions between the notches constituting in effect peripheral teeth. Motion is communicated directly and positively to the disk by means of a thread or lip, 9, formed on the periphery of the tyer-driving Wheel E, and engaging in the notches of the disk. As shown in this figure, the thread for a portion of its length lies in a plane at right angles to the axis-or, in other words, in line with the plane of rotationwhile for the remainder of its length it lies obliquely or s'pirally in relation to its axis. During the rotation of the wheel the oblique portions of the thread rotate the clamping-disk; but the straight portion passing the disk causes the same to remain at rest. In machines of the ordinary construction the Wheel E is compelled to revolve during the time that it is required to have the disk remain at rest; hence the necessity of employing the straight portion of the lip or thread. In machines which admit of the wheel E being revolved intermittingly, and only when the disk is to be turned, the thread 9 may be spiral or oblique throughout its entire length, as the stoppage of the wheel at the proper timewill in such case enable the oblique thread to hold the disk in position.

In order to admit of the clamping-disk being located immediately above or behind the tying-bill, as required, and as represented in the drawings, and at the same time to admit of the wheel E being brought in the proper proximity thereto, the periphery of the wheel is curved or made concave in cross-section to correspond with the circumference of the disk, as plainly shown. The wheel E is provided,

in addition to the other features named, with a socket or bearing, h, adapted to receive one of the usual ejector-arms, F, by which the delivery of the bound bundles fromthe machine is effected.

It will be observed from the foregoing description that the single wheel E serves the three purposes of imparting the intermittent motion directly to the tyer, of imparting a like motion directly to the clamping-disk, and of operating the ejector-arm.

Passing now to the construction represented in Fig. 2, it will be found very similar to that illustrated in the preceding figure. The frame, tyer, disk, and driving-wheel are constructed and arranged in substantially the same manner. The driving-wheel E is constructed, as in the first case, to operate the tyer, and provided with the thread .or lip to actuate the clamping-disk. Thethread,however,instead of acting directly upon the disk, as in the first example, acts upon an intermediate pinion, G, which in turn acts upon a pinion formed on the under side of the clamping-disk. This' arrangement causes the clamping-disk to be revolved in the opposite direction from that first described, in consequence of which the co-opcrating clamp or arm H is placed at the front instead of at the rear edge of the disk. The thread or lip imparts an intermittent motion to the pinion G, which in turn impartsa corresponding motion to the clamping-disk. Referring to Fig. 3, the driving-wheel there in represented is similar to those represented in the preceding figures, except that it has, instead of a single thread, three threads or lips lying side by side to act successively in turning the disk. By thus using a plurality of threads they may be given a rapid pitch and caused to turn the disk quickly at the proper instant. In connection with the wheel thus constructed I prefer to employ the disk with allits notches of sufficient depth to admit the threads, as in Fig. 4. In this device the cord will enter the alternate notches in the disk, while the actuating threads or lips will enter all the notches. Inasmuch as the wheel revolves during the time or a part of the time that the disk is at rest, it is desirable to prevent the threads from acting against the disk at such time, and thereby producing unnecessary wear and friction. For this purpose the thread is given at the point 70, where its turning action on the disk ceases, a curvature forward in advance of the following portion. This advanced portion of the thread turns the disk so far ahead and causes it to stop in such position that the following portion of the thread passes without contact with the disk until the point is reached at which it again acts to turn the diskin other words, the disk is turned ahead sufficiently to leave a free'space, as shown at i, Fig. 4., in advance of that portion of the thread which. passes through the disk while the latter is at rest.

It is to be observed that the thread employed in my device upon the driving-wheel remains continuously in engagement, and

serves the twofold purpose of imparting the rotary motion to the clampingplate and also of locking the plate against rotation during the intervening periods of time, thus avoiding the necessity of employing the delay-surfaces or other locking devices commonly required. It has the action stated,whether employed to operate directly upon the clampingdisk, as in Figs. 1 and 3, or through the intermediate pinion represented in Fig. 2. The preferred arrangement,and that which is commonly adopted, is to have the thread engage directly with the periphery of the clampingdisk. I believe myself to be the first to provide a tyer-operating wheel with a thread or lip which acts directly or without intervening parts on the clamping-disk, and thefirst to provide a tyer-operating wheel with a thread which operates continuously upon the clamping-disk, so as to answer the double purpose of rotating the disk and of locking the same against rotation when required.

I am aware that it is old to providethetyeroperating wheel with teeth which impart motion to a wheel which is in turn connected by an intermediate shaft with the clampingwheel, the pinion and wheel being provided with delay-surfaces to lock the pinion. I am also aware that a tyer-operating wheel has been provided with a cam-surface, which acts through intermediate levers, pulleys, and other devices to operate a clamping-disk. I am also aware that a clamping-disk has been revolved by means of a worm-wheel and worm, the latter being in turn actuated through a shaft from a pinion provided with teeth and delay-surfaces, actuated by corresponding teeth and delay-surfaces on the tyer-driving wheel, and to the arrangements above specified I make no claim. The construction which Ihave devised is advantageous because of its exceeding simplicity and of the fact that it insures a positive action of the parts.

I am also aware that a clamping-disk has been operated by means of a spiral thread formed on a special wheel, which is in turn driven by gears from the shaftB of the tyerdriving wheel, and to such construction I lay no claim.

It will of course be understood that the position of the thread upon the driving-wheel may be varied as the relations of the parts may require, and that the thread may be either on the circumference or on the side face.

Having thus described my invention, what I claim is q 1. A rotary tyingdevice and an actuatingpinion thereon, combined with a cord-clamping disk having notches in its periphery, and an actuating -wheel provided with teeth to drive the pinion, and also with a thread or lip engaging directly with the disk, whereby the single wheel is caused to operate both the tyer and the clamp without the use of intermediate parts.

2. In combination with the cord-clamping disk and the tyer provided with a pinion,

the actuating-wheel provided with teeth to actuate the pinion, and also with the continuously-acting thread having a portion of its length arranged spirally, and the remainder in a plane at right angles to its aXis, whereby it is caused to impart an intermitting rotation to the disk, and to hold the same during the proper intervals against rotation.

3. A rotary cord-clamping disk, with driving-teeth thereon, combined with a drivingwheel having its periphery curved transverse- I 1y to encircle the disk and provided with a thread or lip to actuate the same.

4:. In combination with the clamping-disk provided with peripheral notches, the actuating-wheel provided with the continuouslyacting thread or lip, which is advanced or curved forward at the point is, as and for the purpose described.

5. The wheel E, provided with teeth and delay-surfaces, and with a spiral thread, substantially as described, whereby it is adapted to serve the double purpose of operating a tyer and of imparting motion directly or iiidirectly to a cord-clamping device.

WILLIAM BUTTERFIELD.
